Another potential option you may have for lowering your student loan interest rate is to consolidate multiple student loans — especially those student loans with higher rates of interest — into one single
private loan with a lower interest rate.
I am trying to get my wife to move into this house with me so we can do an 80 % LTV 30y
fixed loan with a low interest rate, but otherwise I'd do a 30y fixed 75 % LTV investment loan.
